Prometheus is an excellent open-source monitoring system which allows us to collect metrics from our applications and stores them in a database, especially a time-series based DB. The biggest advantage of Prometheus is the query language it provides for data processing.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS.
